If his legs are even comparable to early his early 2000's version he'll do well.
What about what appeared to be loose skin issues on Kev's legs? Do you think he can overcome that with more muscle pushing against the skin? Or would Kev be of the mind to get surgery to overcome that?
Regardless, I still fear for Kev's health. I believe both of his parents passed away before they turned 70, and Kev is fast approaching that age. He should just enjoy his retirement.
What sucks about bodybuilding is that you get the most benefit from steroids, and so as a result, in retirement, everyone knows. Everyone sees the change. While Wayne Gretzky just looks like a healthy 57-year-old man who gets to live the next 30 years signing autographs and enjoying tea or coffee [or other niceties] with family and friends, Ronnie Coleman - bodybuilding's equivalent, if anyone was one - can barely walk, despite being three years younger, and Greg Kovacs is no longer alive.
It would be debatable, but I think a majority of men would say that bodybuilding's most successful champion ever outside of bodybuilding, Arnold Schwarzenegger, likely led a "better" life than Wayne Gretzky, if living like a rock star defines life success. To be honest, I think even Wayne himself would rather have his quieter life than the life of Arnold. So while there definitely are some major success stories in bodybuilding, I think it would be awful to be in retirement and have everyone see you as a fraction of your former self [I am referring to the Ronnie vs. Wayne comparison, not Arnold vs. Wayne].
Still though, on some level I feel sorry for Kev, only due to the health risks associated with carrying that much mass while approaching 70.
